Stock market tracker for hackers.

mop: track stocks the hacker way

A command-line utility that displays current information on select markets and individual stocks.

Installing mop from source

Ensure GO language is installed. Download from: https://go.dev/dl/ and the $GOPATH is set then:

git clone https://github.com/mop-tracker/mop
cd mop
go build ./cmd/mop
./mop

Using mop

By default, mop refreshes quotes and market data on a 5 minute (600s) interval. These values can be changed in the .moprc file.

For demonstration purposes mop comes preconfigured with a number of stock tickers. You can easily change the default list by using the following keyboard commands:

   +                  Add stocks to list
   -                  Remove stocks from list
   ? h H              Display this help screen
   f                  Set filtering expression
   F                  Unset filtering expression
   g G                Group stocks by advancing/declining issues
   o                  Change column sort order
   p P                Pause market data and stock updates
   t                  Toggle timestamp on/off
   Mouse Scroll       Scroll up/down
   PgUp/PgDn          Scroll up/down
   Up/Down arrows     Scroll up
   j J                Scroll up
   k K                Scroll down
   q esc              Quit mop

When prompted please enter comma-delimited list of stock tickers.

The list and other settings are stored in the profile file (default: .moprc in your $HOME directory).

No Timestamp

With Timestamp

Expression-based Filtering

Mop has an in realtime expression-based filtering engine that is very easy to use.

At the main screen, press f and a prompt will appear. Write an expression that uses the stock properties.

Example:

last <= 5

This expression will make Mop show only the stocks whose last values are less than $5.

The available properties are: last, change, changePercent, open, low, high, low52, high52, volume, avgVolume, pe, peX, dividend, yield, mktCap, mktCapX and advancing.

The expression must return a boolean value, otherwise it will fail.

For detailed information about the syntax, please refer to Knetic/govaluate#what-operators-and-types-does-this-support.

To clear the filter, press Shift+F.

You can specify the profile you want to use by passing -profile <filename> to the command-line.

mop's Issues

Filters not working

It seems like the filter only works for the Ticker column, where you can match a string: ticker=="IBM" If you filter on a numerical column, like in the example in the readme (last <= 5), the filter fails and is cleared in the next cycle. An example is below, where I try to filter on the "last" value.

Here is the filter expression being entered:

No results are returned. The display goes blank for a cycle, and then the filter is cleared by one of my earlier patches.

Note that filtering on a string works, e.g. filtering on ticker=="C":

Custom column sort order

I was wondering whether a custom option can be in implemented maybe by using an external textfile with the stocks displaced chronologically as one would wish to view them in terminal.

Would this be possible?

Thank you.

Help how to watch china stock market

Excuse me ! I wonder how can i know china stock market ?

current timezone in top right corner (not time) changes for every quote-refresh

"1" is added to current time for every quote-refresh.
It at least seem to occur every 5s. I couldn't immediately find the cause in the code.

EDIT:
... and, the timezone seems to flip between "PST" (when 1 is added) and "CEST". The actual timestamp does however not seem to flip between CEST and PST timezone.

EDIT2:
It seems that it's not the value "1" that is added to the time string - as it's also happening now (at 3 o' clock) with a leading "3". Maybe it's because the string is one character shorter (PST vs CEST) and is written "on top" of the other string - without removing it?

Maybe you have another idea?

Make issues on Mac

Issue Description:

I downloaded mop by cloning this git repository. Then I issued the make command from the root folder of this repo. I see the following error after trying to make:

go run ./cmd/mop/main.go
cmd/mop/main.go:9:2: cannot find package "github.com/michaeldv/termbox-go" in any of:
	/usr/local/Cellar/go/1.11.4/libexec/src/github.com/michaeldv/termbox-go (from $GOROOT)

make: *** [run] Error 1

I installed go from the homebrew package manager so all my symlinks are in /usr/local/Cellar/go/1.11.4/bin.

My path environment variable is:

What can I do to remedy this error? Thank you.

Error on Mac

Followed the instructions about setting up go workspace etc...

go get github.com/mop-tracker/mop/cmd/mop

results in

Mop went blank after fullscreen

After hours and pre hours trading support

Love this program. Just started using it. I always check this program to verify the prices I see online, because sometimes web pages stick and need to be refreshed. Works great for the main trading session of the day, but there are actually three trading session, the pre hours, regular hours and after hours sessions. I know we have the change % -which incidentally would be nice to be able to move that to the left rather then have to set a 13 font size on the terminal which is too small for anyone who's farsighted to see without strain-, we have the change %, but it would be great to see the actual values during all three trading sessions, not just the main session. Maybe I'll give the program a go myself. :)
Thanks! Bill

error: editor.regex.Split undefined

Tried installing mop this morning:

$ go get github.com/michaeldv/mop
# github.com/michaeldv/mop
go/src/github.com/michaeldv/mop/line_editor.go:204: editor.regex.Split undefined (type *regexp.Regexp has no field or method Split)

Should this variable be type *regexp instead of *regexp.Regexp?

buy mistake i added wrong filter. how can i clear that filter and run it.
not able to find '.moprc'

go get gives the following error

the only path i have is in my .bashrc and its this one

Mop on RPI CPU Issue ?

Hi,
I'm running mop on a raspberry Pi B+.
Don't know if this is a real isssue or not, but mop is using about 100% of the cpu when running on raspberry.

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
1071 root 20 0 848888 11256 5496 S 97,1 2,3 32:12.37 mop
Ps : I've added all the PA(PARIS) stock tickets in mop (about +200)

Have someone reproduced this issue ?
Thanks in advance

bad filter crashes system in way difficult to recover

If one enters a invalid filter, the program terminates, AFTER writing the bad filter to the config file. Thus, any attempt to restart the program will fail until the config file is manually edited.

More fundamentally, a keyboard user-error shouldn't panic the program to crash.

And an invalid setting should not be save to disk.

I'm not a go programmer and don't have development set up, but eyeballing the code, I wonder if the fix is to alter line 137 in file profile.go from:

panic(err)

to:

profile.SetFilter("")

In other words, recursively call the function with a reset value, similar to what would happen when a user enters 'F'

Entering some incorrect ticker values will make mop not display the stocks properly.

Entering, for example SHO{ (instead of SHOP), will result in mop displaying no ticker values at all.
The values entered by the user should be sanitized before being treated. I think something like [A-Z][A-Z_\-\.]* or something similar (maybe limiting the number of special characters too) should work.

Error fetching stock quotes

Error fetching stock quotes...
Get http://download.finance.yahoo.com/d/quotes.csv?s=AAPL+ALXN+AMZN

Any fixes or alternative sources?

A way to print as output once and exit, rather than updating?

This program would be excellent to use in scripts; if the output could be piped into other commands. As-is, I cannot find a way to save the output.

error fetching market data

New source for ticker data needed

http://download.finance.yahoo.com/d/quotes.csv?s=%s&f=sl1c1p2oghjkva2r2rdyj3j1 is no longer serving quote data. The following message is displayed:

It has come to our attention that this service is being used in violation of the Yahoo Terms of Service. As such, the service is being discontinued. For all future markets and equities data research, please refer to finance.yahoo.com.

In short, a new source for ticker data is needed to replace yahoo. There will likely be additional changes required to support any new data source.

Unable to parse http://money.cnn.com/data/markets/

Looks like they've updated their HTML. Do the developers have a good engineering estimate for this? I'd be interested in submitting a fix if this is something a relative Go-newbie could figure out.

Version not properly bumped

Several places wtill showing 0.2.0 as the current version in the code. I created PR #94 to address the situation. However, accepting the changes might make the actual the version 1.0.1. Feel free to ignore my PR and fix on your own.

Mop "breaks" once in a while - likely when there is a problem with fetching from yahoo??

Quite often (as in, several times a day) I get the following (or similar?!) error:

"Get https://query1.finance.yahoo.com/v7/finance/quote\?symbols\=DANSKE.CO,ERIC-B.ST,FPKPEN.CO,SSO.OL,VWS.CO\&range\=1d\&interval\=5m\&indicators\=close\&includeTimestamps\=false\&includePrePost\=false\&corsDomain\=finance.yahoo.com\&.tsrc\=finance: read tcp 172.21.140.214:61687->87.248.1"

It seems like the ending of the error has been cropped off. But it was as much as I could retrieve.

The top left corner says: "Error fetching market data..."

Just below, it says:
"Get https://money.cnn.com/data/markets/: read tcp 172.21.140.214:62979->199.232.41.67:443: read: network is downt"

Screenshot

It overlays/replaces the first line of the stocks in my portfolio.

Mop doesn't update the quotes/info when this error is present.

The clock in top right corner of mop still runs (as far as I remember).

It can be "circumvented" by just closing mop, and starting it again. It immediately works when restarted.

Could one add a "try: / except:" (or whatever that would be in the go-language) statement around the retrieval of information from yahoo, so the program doesn't break when there is an error?

Feature Request: Tracking Portfolio

Let me thank you for MOP. It is awesome that I can track the stock market form the command line. Superb. 🍻

I am wondering if you are planning to add some portfolio tracker to it? Let's say I buy X mount of stock at certain price and I want to track how much I am loosing or winning.

I failed something in installation or is this an issue?

Pulling Analyst ratings to tracked stocks

Is it possible to pull analyst ratings for tracked stocks? Most stocks on Yahoo have:
https://finance.yahoo.com/quote/SQ/analysis

Cannot make on Ubuntu 16.04

I would like to use mop as it looks really good.
I installed the go language and added export GOPATH="$HOME/workspace" to my .bashrc
I then ran source ~/.bashrc

I followed the instructions on the mop-tracker github page and get as far as:
cd $GOPATH/src/github.com/michaeldv/mop

When I run make make build or make install I get a couple of error messages:

~/workspace/src/github.com/michaeldv/mop $ make make: *** No targets specified and no makefile found. Stop.

~/workspace/src/github.com/michaeldv/mop $ make build make: *** No rule to make target 'build'. Stop.

~/workspace/src/github.com/michaeldv/mop $ make install make: *** No rule to make target 'install'. Stop.

Any idea what is wrong or how I can fix it?

Thank you

read in multiple .moprc files

First, hats off to you for providing such a great lightweight program!

Just wondering if it's easy to provide a feature to read in multiple .moprc files? For example, if I create a one .moprc file for high-tech stocks, and create another .moprc for finance stocks, then if I just want to check all the financial stocks, I just need to open the corresponding .moprc file.

Thanks!!

Terminal Scrollbar

The terminal scrollbar does not work.

.moprc has more tickers than the 'screen' can handle.

Therefore, 36/45 are visible at anytime and cannot scroll the visualise the remaining.

Loading mop with invalid .moprc will wipe .moprc file

If you modify the .moprc file by and and mistakenly leave a wrong coma somewhere, the whole file will get wiped.
If the .moprc file is malformed, I would expect the program to let me know and leave the .moprc file untouched.

Sorting "change" column does not evaluate decimal value correctly

Version: Master as of 4-6-2020

Overview of Issue: I was sorting the change column with screen shot attached. As you can see "TSLA" at the time is 29.48 and is greater than "KMX" which is at 3.32. "TSLA" is higher and it appears is being evaluated by the the decimal from left to right and not the whole value.

Time zone not consistent (is PST, should be EST)

The correct local time is displayed, but the displayed time zone is different (and does not match the output of "date" on local computer). For instance, it is currently 2:24 EST but the time displayed is 2:24 PST. I looked for a configuration file, but didn't see anything in .moprc.

default colors are bad for the colorblind

The two hues used in the default colors are difficult to distinguish by people with red/green colorblindness (1 in 12 males). I love this terminal app concept, but consider defaulting to magenta and green or something more accessible for people with color vision deficiencies.

Change output colors

Is it possible to put up/down color settings in the .moprc profile, so that we can change colors to suit our schemes?

Currency symbol

When adding tickers from non-US exchanges, the stock price is incorrectly shown as $

For example, AZN.L (listed on the FTSE) should be shown with a price in £ not $.

Shortened (e.g. filtered) quotes list causes screen to not update

If the quotes list is shortened, e.g. by filtering the quotes, then the screen does not update properly. Here's an example.

Full quotes list:

Incorrectly-filtered list:

It should look like this.

Make single-shot to pipe / redirect to other commands

It would be nice if we could get a single snapshot of output by something like
mop --single > output.txt
This would be really handy for scripting alerts and actions based on the output.

filter value does not appear accurate

Here is my default view, snipped to two columns for clarity:

↑Ticker         Last
AMZN        $2736.12
FFIV         $139.11
GOOG        $1397.52
ORCL          $54.95
ZM           $255.19
IBM          $119.47

When I apply a filter such as last < 150

Amazon and Google are filtered out, but I still see Zoom ($255.19):

↑Ticker         Last
FFIV         $139.14
ORCL          $54.92
IBM          $119.41
ORCL          $54.92
ZM           $255.08
IBM          $119.41

Am I misunderstanding the usage of filter, and the value that is represented?

EDIT: After applying a filter, if I quit from mop-tracker and reopen, then the filter appears to be applied correctly. My first thought was some sort of refresh issue, but I waited for a few minutes before stopping mop-tracker.

Here is my .moprc:

{
  "Tickers": [
    "AMZN",
    "FFIV",
    "GOOG",
    "IBM",
    "ORCL",
    "RHT",
    "ZM"
  ],
  "MarketRefresh": 0,
  "QuotesRefresh": 0,
  "SortColumn": 0,
  "Ascending": true,
  "Grouped": true,
  "Filter": "last < 150"
}

Quick Visual Reference: Sparklines

I might take this on.

Maybe some candle sticks, RSI/MACD? Is it not possible and that's why nobody has done it yet? I guess I'll soon find out.
